14.  Samual is driving along a straight and level road straight toward a mountain.  At some point on his trip he measures the angle of elevation to the top of the mountain and finds it to be 21 degrees.  He then drives 1 mile (5280ft) more and measures the angle of elevation to be 35 degrees.  Find the height of the mountain to the nearest foot.
